推荐答案

在可以接受命令行参数的标准 Java 程序中，会有一个类作为整个程序的入口点.该类将有一个静态方法，如下所示:

In a standard Java program that can take command line arguments, there will be a class that acts as the entry point of the whole program. That class will have a static method in it like this:

public class FooBar {
    // ...
    public static void main(String[] arguments) {
        // ...
    }
    // ...
}

参数位于作为该方法参数的数组中，该数组必须具有该签名并且既是公共的又是静态的.如果您使用的是托管引擎或框架，通常会为您处理入口点；您应该查阅其文档以了解如何获取命令行参数(如果可能的话，甚至是合理的).

The arguments are in the array that is the parameter to that method, which must have that signature and be both public and static. If you're using a hosting engine or framework, the entry point is often taken care of for you; you should consult its documentation to see how to get command line arguments (if that is possible at all, or even reasonable).

命令行参数总是字符串.如果你想将它们解释为别的东西，你必须手动转换它们.

Command line arguments are always strings. If you want to interpret them as something else, you've got to convert them manually.
